Guidance for New Motivational Interviewing Trainers When Training Addiction Professionals

Evidence-based practices, such as motivational interviewing (MI), are not widely used in community alcohol and drug treatment settings. Successfully broadening the dissemination of MI will require numerous trainers and supervisors who are equipped to manage common barriers  to technology transfer. The aims of the our survey of 36 MI trainers were: 1) to gather opinions about the optimal format, duration, and content for beginning level addiction-focused MI training conducted by novice trainers and 2) to identify the challenges most likely to be encountered during provision of beginninglevel MI training and supervision, as well as the most highly recommended strategies for managing those challenges in addiction treatment sites. It is hoped that the findings of this survey will help beginning trainers equip themselves for successful training experience

The genetic architecture of the human cerebral cortex

The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area cluster near genes in Wnt signaling pathways, which influence progenitor expansion and areal identity. Variation in cortical structure is genetically correlated with cognitive function, Parkinson's disease, insomnia, depression, neuroticism, and attention deficit hyperactivity disorder
